Description

Technical Field

[0001] This invention relates to neck support devices, and more particularly to a lightweight neck brace and its application. Background Technology

[0002] The neck connects the head and torso, supporting the relatively heavy head. With the help of the neck, the head can turn flexibly left and right, and up and down; however, the neck also bears the pressure from the weight of the head. If the head remains in a fixed position for a long time, it will put a significant strain on the neck; for example, people who work at a desk for long periods often experience neck pain. More seriously, maintaining poor posture for extended periods, such as students who, during development, may place their heads too close to books or desks, can lead to vision problems like nearsightedness, while simultaneously placing undue pressure on the neck.

[0003] Neck braces maintain the neck at a specific angle and distribute the weight of the head to the torso because the brace itself is supported by the shoulders, thus reducing the burden on the neck. However, current neck braces are often designed for patients with neck or head conditions requiring rehabilitation. This results in two main issues: firstly, they are bulky, supporting the head on the shoulders and restricting its movement; secondly, the neck braces themselves are not adjustable, keeping the head and neck at a fixed angle, making it difficult for users to tilt their heads up or down, thus limiting head movement and hindering their rehabilitation and health maintenance benefits. Clearly, this type of neck brace is primarily targeted at patients with pre-existing neck or head conditions. It is unsuitable for healthy individuals seeking neck protection.

[0015] Two adjustment sections are located at the connection between the first support arm and the second support arm of the head support and the support. The head support is rotatably connected to the support by means of the adjustment sections, such that the size of an included angle formed between the head support and the support is adjustable. The lightweight neck brace has an adjusted state and a free state, and is operable to switch between the adjusted state and the free state. In the adjusted state, the head support can only be adjusted in a direction away from the support, so that the height of the supported head cannot be lowered. In the free state, the head support can be adjusted arbitrarily in a direction away from or towards the support.

[0016] According to one embodiment of the present invention, the adjustment part includes an outer rotating member and an inner rotating member, wherein the outer rotating member is mounted on the head support part, and the inner rotating member is mounted on the support part, wherein the inner wall of the outer rotating member forms a receiving space, the inner rotating member is received in the receiving space, the inner wall of the outer rotating member protrudes to form at least two unidirectional teeth, wherein the inner rotating member engages with the outer rotating member and the inner rotating member and the outer rotating member can rotate relative to each other and in one direction, in the adjustment state, the inner rotating member is limited to being able to rotate only in one direction relative to the outer rotating member, and in the free state, the inner rotating member can be released to rotate freely relative to the outer rotating member.

[0017] According to one embodiment of the present invention, the adjustment part includes an outer rotating member and an inner rotating member, wherein the outer rotating member is mounted on the support part, and the inner rotating member is mounted on the head support part.

In the adjustment state, the inner rotating member is limited to unidirectional rotation only relative to the outer rotating member. In the free state, the inner rotating member can be released to rotate freely relative to the outer rotating member.

[0018] According to one embodiment of the present invention, the inner rotating member includes a fixed base and a connecting arm, wherein the connecting arm has a connecting end and a free end, the connecting end of the connecting arm is connected to the fixed base, and the free end of the connecting arm is close to the tooth of the outer rotating member. In the adjusted state, the free end of the connecting arm is engaged with the tooth and can only disengage from one tooth in one direction and then engage with the next tooth. In the free state, the free end of the connecting arm disengages from the tooth, so that the outer rotating frame and the inner rotating member can rotate freely.

[0019] According to one embodiment of the present invention, the adjustment part further includes an adjustment member, wherein the inner rotating member is limited within the adjustment member. In the adjusted state, the adjustment member limits the inner rotating member to press the connecting arm against the teeth of the outer rotating member. In the free state, the adjustment member limits the inner rotating member to maintain a gap between the teeth of the connecting arm and the outer rotating member. By changing the position of the adjustment member, the lightweight neck brace can be switched between the adjusted state and the free state.

[0020] According to one embodiment of the present invention, the connecting arm is elastically connected to the fixed base.

[0021] According to one embodiment of the present invention, the number of connecting arms is two, the fixing base has a first end and a second end, one of the connecting arms is connected to the first end and extends toward the second end, and the other connecting arm is connected to the second end and extends toward the first end, with the two connecting arms located on opposite sides of the fixing base.

[0026] According to one embodiment of the present invention, the lightweight neck brace further includes a fixing portion, wherein the fixing portion extends between the two ends of the head support portion to form a wearable channel of adjustable size.

[0027] According to one embodiment of the present invention, the head support includes a first support arm and a second support arm, wherein the first support arm is pivotally connected to the second support arm so as to be folded toward the second support arm.

[0028] According to one embodiment of the present invention, the first support arm of the support is pivotally connected to the second support arm so as to be folded toward the second support arm.

[0029] According to another aspect of the present invention, the present invention provides a method for adjusting a lightweight neck brace, comprising the following steps:

[0030] A lightweight neck brace has a head support portion and a support portion that can be switched between an adjusted state and a free state by means of an outer rotating member and an inner rotating member of an adjustment portion. The head support portion and the support portion are rotatably connected by the adjustment portion. The head support portion is adapted to support the head and is supported by the support portion. The support portion is adapted to be supported by the torso. When the inner rotating member is engaged with the outer rotating member, the lightweight neck brace is in the adjusted state. The head support portion of the lightweight neck brace can rotate unidirectionally away from the support portion, but cannot rotate towards the support portion. When the inner rotating member is disengaged from the outer rotating member, the lightweight neck brace is in the free state.

[0043] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0044] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the invention.

[0045] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0046] Reference Appendix Figure 1 To be continued Figure 6 As shown, a lightweight neck brace 1 according to a preferred embodiment of the present invention is illustrated.

[0047] The lightweight neck brace 1 supports the user's head against the torso, reducing pressure on the neck from the weight of the head. Furthermore, the lightweight neck brace 1 itself is designed to be lightweight and adjustable to suit the user's needs. Compared to previous bulky, one-piece neck braces, the lightweight neck brace 1 is much more convenient to use.

[0048] In detail, the lightweight neck brace 1 includes a head support 10 and a support 20, wherein the head support 10 is adapted to support the user's head in a desired position, the head support 10 can be supported by the support 20, and the support 20 can be supported by the user's torso, for example, by the user's chest, shoulders and / or abdomen.

[0049] It is understood that the lightweight neck brace 1 can be applied not only to humans but also to animals, as long as adaptive adjustments are made to the head support portion 10 and the support portion 20. Such modifications are still within the protection scope of this invention.

[0050] The lightweight neck brace 1 forms a wearing channel 100, through which a user's neck can be held while wearing the lightweight neck brace 1. The size of the wearing channel 100 is adjustable to accommodate different users. Optionally, the user's head can be held within the wearing channel 100 while wearing the lightweight neck brace 1.

[0051] Reference Appendix Figure 1 and Figure 2The support portion 20 includes a first support arm 21 and a second support arm 22, wherein the first support arm 21 and the second support arm 22 extend outward from the head support portion 10 and are connected to each other at one end. Specifically, one end of the first support arm 21 is connected to the head support portion 10, one end of the second support arm 22 is connected to the head support portion 10, and the other end of the first support arm 21 is connected to the other end of the second support arm 22. The first support arm 21, the second support arm 22, and the head support portion 10 of the support portion 20 form a stable triangular support structure, which can stably support the head against the torso.

[0052] The support portion 20 can form an angle with the head support portion 10, and the size of the angle is adjustable. The lightweight neck brace 1 further includes at least one adjustment portion 30, which is disposed at the connection between the support portion 20 and the head support portion 10, so that the angle between the support portion 20 and the head support portion 10 can be adjusted, and the head support portion 10 and the support portion 20 can be held in the adjusted position. Preferably, in the attached... Figures 1 to 6 In this preferred example of the lightweight neck brace 1 shown, the lightweight neck brace 1 includes two adjustment parts 30, one of which is disposed at the connection between the first support arm 21 and the head support part 10, and the other of which is disposed at the connection between the second support arm 22 and the head support part 10.

[0053] The head support 10 can be folded toward the support 20, so that the lightweight neck brace 1 can be folded into a smaller size, making the lightweight neck brace 1 easy to carry. The head support 10 can also be supported at a fixed angle on the support 20, so that the head support 10 can support the head at a desired angle.

[0054] Furthermore, the lightweight neck brace 1 has the function of preventing myopia. When a user sits in front of a table or computer, the user's head tends to lean towards the table or computer. Over time, this may lead to myopia. The head support part 10 and the support part 20 of the lightweight neck brace 1 can be adjusted and fixed at a certain angle to prevent the head from leaning towards the table or computer, thereby preventing myopia.

[0055] Furthermore, the head support portion 10 and the support portion 20 of the lightweight neck brace 1 are configured for unidirectional adjustment. When the lightweight neck brace 1 is worn on the user's body, the head support portion 10 cannot be adjusted toward the support portion 20 to prevent the head from lowering further, thereby helping to protect the user's vision. The head support portion 10 can be adjusted away from the support portion 20 to suit different user postures and usage needs.

[0056] It is worth noting that another advantage of setting the head support 10 and the support 20 to be unidirectionally adjustable is that when the head is supported by the head support 10 and has a tendency to move downwards, since the head support 10 cannot move toward the support 20, the head support 10 is restricted to moving only away from the support 20. This reduces the possibility that the head may gradually move downwards without the person realizing it due to insufficient connection strength between the head support 10 and the support 20.

[0057] The lightweight neck brace 1 has an adjustable state and a free state. In the adjustable state, refer to the attached... Figure 3 and attached Figure 4 The head support portion 10 of the lightweight neck brace 1 is unidirectionally adjustable relative to the support portion 20 and can be fixed in the adjusted state. The head support portion 10 cannot move toward the support portion 20 to ensure that the head is securely supported by the head support portion 10. In the free state, refer to the attached... Figure 5 and attached Figure 6 The head support portion 10 of the lightweight neck brace 1 can be adjusted towards the support portion 20 or away from the support portion 20. That is, the rotation direction of the head support portion 10 is unrestricted. The head support portion 10 can be adjusted to fold into the support portion 20. It is understood that the unidirectional adjustment of the head support portion 10 and the support portion 20 in this invention means that when the lightweight neck brace 1 is in the adjusted state, the head support portion 10 of the lightweight neck brace 1 is only allowed to adjust in one direction relative to the support portion 20.

[0058] By adjusting the adjustment part 30, the lightweight neck brace 1 can switch between the adjusted state and the free state. Specifically, when no external force is applied to the adjustment part 30, the lightweight neck brace 1 is in the adjusted state; correspondingly, when an external force is applied to the adjustment part 30, the lightweight neck brace 1 can switch from the adjusted state to the free state.

[0059] In detail, see attached document. Figure 2The adjustment part 30 includes an outer rotating member 31 and an inner rotating member 32, wherein the outer rotating member 31 is disposed on the support part 20, and the inner rotating member 32 is disposed on the head support part 10, and the inner rotating member 32 is rotatably connected to the outer rotating member 31. By rotating the outer rotating member 31 and the inner rotating member 32, the included angle between the support part 20 and the head support part 10 is adjusted. Optionally, the outer rotating member 31 is disposed on the head support part 10, and the inner rotating member 32 is disposed on the support part 20.

[0060] Continue to refer to the appendix Figure 2 The head support portion 10 has two corresponding ends, wherein the inner rotating members 32 of the two adjusting portions 30 are respectively disposed at each end of the head support portion 10, and the outer rotating members 31 of the two adjusting portions 30 are respectively disposed at the end of the first support arm 21 and the end of the second support arm 22, wherein each inner rotating member 32 is rotatably connected to each outer rotating member 31, such that each end of the head support portion 10 is disposed at the end of the first support arm 21 and the end of the second support arm 22 of the supporting portion 20 through each adjusting portion 30. Further, the outer rotating member 31 forms a receiving space 310, wherein the inner rotating member 32 is located in the receiving space 310 of the outer rotating member 31. The outer rotating member 31 has an inner wall, wherein at least a portion of the inner wall is recessed to form at least two one-way grooves 311. The inner rotating member 32 can be rotated to engage with the one-way grooves 311 of the outer rotating member 31. When the outer rotating member 31 or the inner rotating member 32 is subjected to a force, the inner rotating member 32 can unidirectionally disengage from one of the one-way grooves 311 and then engage with the next one-way groove 311.

[0061] More specifically, when the lightweight neck brace 1 is in the adjusted state, the inner rotating member 32 is originally engaged with one of the one-way grooves 311 of the outer rotating member 31 to keep the head support 10 fixed relative to the support 20. Applying a force to the inner rotating member 32 or the outer rotating member 31 causes the inner rotating member 32 to disengage from one of the one-way grooves 311 and then enter the next one-way groove 311. The head support 10 returns to its fixed state relative to the support 20, and the position of the head support 10 relative to the support 20 has been adjusted. The included angle between the head support 10 and the support 20 is widened.

[0062] The outer rotating member 31 can be implemented as a toothed ring, with unidirectional toothed grooves 311 formed on the inner wall of the outer rotating member 31. There are multiple unidirectional toothed grooves 311, and they are symmetrically arranged.

[0063] The inner rotating member 32 has at least one connecting arm 321, wherein the connecting arm 321 can engage with the one-way toothed groove 311 of the outer rotating member 31. The number of connecting arms 321 can be two or more. Adjacent connecting arms 321 maintain a certain interval. In this embodiment, two connecting arms 321 are implemented, each capable of engaging with the one-way toothed groove 311 of the outer rotating member 31, and the two connecting arms 321 are implemented in a centrally symmetrical manner.

[0064] In detail, the inner rotating member 32 includes a fixed base 322 and connecting arms 321, wherein two connecting arms 321 extend from the fixed base 322, and the fixed base 322 is fixed to the head support portion 10. Each connecting arm 321 has a connecting end 3211 and a free end 3212 corresponding to the connecting end 3211, wherein the connecting end 3211 of the connecting arm 321 is connected to the fixed base 322, and the free end 3212 of the connecting arm 321 abuts against the one-way toothed groove 311 of the outer rotating member 31. Preferably, the connecting end 3211 of the connecting arm 321 extends integrally outward from the fixed base 322 in a suspended manner, allowing the connecting arm 321 to deform towards the fixed base 322 under pressure and return to its initial state when the pressure is removed.

[0065] The connecting arm 321 has a support surface 3213, which can be formed at the free end 3212 of the connecting arm 321. The support surface 3213 can be abutted against the one-way toothed groove 311 of the outer rotating member 31. The support surface 3213 can be an inclined surface, and the inclined surface of the support surface 3213 can cooperate with the inclined surface of the one-way toothed groove 311 of the outer rotating member 31.

[0066] The inner rotating member 32 is mounted on the outer rotating member 31, and the connecting arm 321 is pressed against the inner wall of the outer rotating member 31. When the inner rotating member 32 and the outer rotating member 31 rotate relative to each other, the inner rotating member 32 can be rotated until the support surface 3213 of the connecting arm 321 engages with the one-way groove 311 of the outer rotating member 31. When the inner rotating member 32 and the outer rotating member 31 rotate further relative to each other, the inner rotating member 32 can be rotated to allow the support surface 3213 of the connecting arm 321 to engage with the next one-way groove 311 of the outer rotating member 31.

[0067] The extension direction of the connecting arm 321 is set along the inner wall of the outer rotating member 31, or the extension direction is set along the rotation direction of the inner rotating member 32 and the outer rotating member 31. When the outer rotating member 31 and the inner rotating member 32 rotate relative to each other, since the direction of the connecting arm 321 is along the rotation direction of the outer rotating member 31 and the inner rotating member 32, the force on the connecting arm 321 is mainly generated by the squeezing effect of the free end 3212 of the connecting arm 321, while the force on the connection between the connecting arm 321 and the fixed seat 322 is smaller. This helps to reduce the wear at the connection between the connecting arm 321 and the fixed seat 322 of the inner rotating member 32, and also facilitates the rotation of the outer rotating member 31 and the inner rotating member 32, reducing resistance.

[0068] The user can rotate the outer rotating member 31 and the inner rotating member 32 with a small amount of force. When the inner rotating member 32 is rotated until the support surface 3213 of the connecting arm 321 is aligned with the one-way tooth groove 311 of the outer rotating member 31, the head support 10 and the support 20 cannot rotate in opposite directions, so the head support 10 can be stably held in the adjusted position.

[0069] In other words, the outer rotating member 31 is mounted on the support portion 20, and the inner rotating member 32 is mounted on the head support portion 10. The outer rotating member 31 and the inner rotating member 32 rotate relative to each other, and can only cause the head support portion 10 to rotate in a direction away from the support portion 20 when the lightweight neck brace 1 is in the adjusted state.

[0070] Because the supporting surface 3213 of the connecting arm 321 of the inner rotating member 32 is pressed against the one-way toothed groove 311 of the outer rotating member 31, the outer rotating member 31 and the inner rotating member 32 cannot rotate freely clockwise or counterclockwise. The inner rotating member 32 can only rotate relative to the outer rotating member 31 along the direction of the one-way toothed groove 311. When the inner rotating member 32 rotates along the direction of the one-way toothed groove 311, the head support portion 10 rotates away from the support portion 20. When the inner rotating member 32 is rotated to the point that the supporting surface 3213 of the connecting arm 321 of the inner rotating member 32 engages with the one-way toothed groove 311 of the outer rotating member 31, the head support portion 10 is fixed to the support portion 20, and the head support portion 10 cannot rotate towards the support portion 20.

[0071] Continue to refer to the appendix Figure 2 The fixing base 322 has a first end 3221 and a second end 3222 corresponding to the first end 3221. One connecting arm 321 is connected to the first end 3221 and extends in a suspended manner toward the second end 3222, and the other connecting arm 321 is connected to the first end 3221 and extends in a suspended manner toward the second end 3222. In other words, the free end 3212 of the connecting arm 321 connected to the first end 3221 and the second end 3222 maintain a certain distance to allow the connecting arm 321 to deform toward the fixing base 322 when subjected to pressure, and the free end 3212 of the connecting arm 321 connected to the second connecting end 3211 and the first end 3221 maintain a certain distance to allow the connecting arm 321 to deform toward the fixing base 322 when subjected to pressure.

[0072] The distance between the free end 3212 of the connecting arm 321 and the fixed seat 322 is variable within a certain range. For example, when the supporting surface 3213 of the connecting arm 321 is pressed against the one-way toothed groove 311 formed by the inner wall of the outer rotating member 31, and disengages from one one-way toothed groove 311 and engages with the next one-way toothed groove 311, the distance between the free end 3212 of the connecting arm 321 and the fixed seat 322 changes.

[0073] When the outer rotating member 31 rotates relative to the inner rotating member 32, the force applied by the outer rotating member 31 can press inwardly against the free end 3212 of the connecting arm 321. The connecting arm 321 has a certain elasticity to maintain its contact with the outer rotating member 31. Since the connecting arm 321 is arc-shaped and extends in the rotation direction of the outer rotating member 31 and the inner rotating member 32, the main force on the connecting arm 321 is at the free end 3212, thereby reducing the force on the connecting end 3211 of the connecting arm 321. From the perspective of the connecting arm 321 of the inner rotating member 32, the connecting end 3211 of the connecting arm 321 will not bring too much resistance during the rotation of the outer rotating member 31 and the inner rotating member 32, thus making it easier for the user to rotate the outer rotating member 31 and the inner rotating member 32.

[0074] Furthermore, to ensure uniform force distribution and smooth rotation of the outer rotating member 31 and the inner rotating member 32, the two connecting arms 321 are configured to be centrally symmetrical, such that when the outer rotating member 31 rotates relative to the inner rotating member 32, the free ends 3212 of the two connecting arms 321 are subjected to the same rotational direction.

[0075] The lightweight neck brace 1 is controllably switchable between the adjusted state and the free state. The adjustment unit 30 further includes an adjustment member 33, wherein the adjustment member 33 is operable to allow the lightweight neck brace 1 to switch between the adjusted state and the free state.

[0076] In the adjusted state, the free end 3212 of the connecting arm 321 of the inner rotating member 32 is confined to the adjusting member 33, so that the inner rotating member 32 remains pressed against the outer rotating member 31, so that the inner rotating member 32 and the outer rotating member 31 cannot rotate freely.

[0077] In the free state, the adjusting member 33 releases the free end 3212 of the connecting arm 321 of the inner rotating member 32, so that the inner rotating member 32 can disengage from the outer rotating member 31, and the inner rotating member 32 and the outer rotating member 31 can rotate in either clockwise or counterclockwise direction.

[0078] In detail, the adjusting member 33 has at least one limiting groove 330, and the connecting arm 321 of the inner rotating member 32 is limited in the limiting groove 330 of the adjusting member 33, thereby preventing it from disengaging from the outer rotating member 31. In this embodiment, since there are two connecting arms 321, there can also be two limiting grooves 330.

[0079] The connecting arm 321 can protrude outward to form a limiting post 3214, which extends in the axial direction. The limiting post 3214 of the connecting arm 321 is limited within the limiting groove 330 of the adjusting member 33.

[0080] The limiting posts 3214 of the two connecting arms 321 can be arranged symmetrically, for example, axisymmetrically. Correspondingly, the two limiting grooves 330 of the adjusting member 33 can also be axisymmetrically arranged. The two connecting arms 321 can be configured to be centrally symmetrically arranged.

[0081] When the adjusting member 33 is adjusted to drive the free end 3212 of the connecting arm 321 to move inward to disengage from the one-way toothed groove 311 of the outer rotating member 31, the two limiting grooves 330 can synchronously drive the two limiting posts 3214 to move, so that the two connecting arms 321 can simultaneously disengage from the outer rotating member 31. At this time, the lightweight neck brace 1 is adjusted to the free state.

[0082] More specifically, the adjusting member 33 includes a first limiting wing 331 and a second limiting wing 332, wherein the first limiting wing 331 forms one limiting groove 330, and the second limiting wing 332 forms another limiting groove 330. The adjusting member 33 further includes a mounting base 333, wherein the first limiting wing 331 and the second limiting wing 332 extend to both sides of the mounting base 333, and the mounting base 333 is adapted to be mounted on the end of the head support portion 10.

[0083] The first limiting wing 331 is connected to the second limiting wing 332, and the mounting base 333 is disposed on one side of the first limiting wing 331 and the second limiting wing 332. The user can operate the head support 10, for example, by pulling the head support 10 outwards, thereby moving the adjusting member 33, and thus releasing the support surface 3213 of the connecting arm 321 of the inner rotating member 32 from the one-way toothed groove 311 of the outer rotating member 31.

[0084] The limiting groove 330 is set to be inclined. When the adjusting member 33 is driven to move by the head support 10, the limiting groove 330 of the adjusting member 33 moves, thereby constraining the limiting post 3214 to move inward, and thus allowing the free end 3212 of the connecting arm 321 to move inward, so that the supporting surface 3213 of the connecting arm 321 disengages from the one-way toothed groove 311 of the outer rotating member 31.

[0085] The extending direction of the limiting groove 330 and the movable direction of the adjusting member 33 can be inclined. The adjusting member 33 has a first position and a second position. When the adjusting member 33 is in the first position, the connecting arm 321 of the inner rotating member 32 is limited by the adjusting member 33 to keep it pressed against the outer rotating member 31. When the adjusting member 33 is in the second position, the connecting arm 321 of the inner rotating member 32 is squeezed away from the outer rotating member 31, so that the inner rotating member 32 is released. When the adjusting member 33 moves from the first position to the second position, the inclined limiting groove 330 maintains the limitation on the connecting arm 321 and pulls the free end 3212 of the connecting arm 321 away from the one-way toothed groove 311 of the outer rotating member 31.

[0086] It is understood that the adjustment member 33 is set to be limited, and the adjustment member 33 can move from the first position to the second position or from the second position to the first position, but it is difficult to extend to other directions.

[0087] More specifically, when the limiting post 3214 of the connecting arm 321 of the inner rotating member 32 is located at the same end of the two limiting grooves 330, the distance between the two limiting posts 3214 is a first distance. When the limiting post 3214 of the connecting arm 321 of the inner rotating member 32 is limited to the other end of the two limiting grooves 330, the distance between the two limiting posts 3214 is a second distance. The first distance is greater than the second distance, so that when the limiting posts 3214 are respectively limited to the two ends of the limiting grooves 330, the relative position of the two limiting posts 3214 changes, thereby changing the position of the connecting arm 321, and thus the lightweight neck brace 1 can switch between the free state and the adjusted state.

[0088] When the two limiting posts 3214 are brought close together, the two connecting arms 321 move toward the fixed seat, thereby moving away from the one-way toothed groove 311 of the outer rotating member 31. The supporting surface of the connecting arm 321 is released from the one-way toothed groove 311, and the lightweight neck brace 1 is in the free state.

[0089] When the two limiting posts 3214 are moved away from each other, the two connecting arms 321 move toward the outer rotating member 31, so that the supporting surface 3213 approaches the one-way toothed groove 311 of the outer rotating member 31 until it is pressed against the one-way toothed groove 311, and thus the lightweight neck brace 1 is in the adjusted state.

[0090] The adjusting member 33 is located on one side of the inner rotating member 32, and the limiting post 3214 is located in the axial direction. Changing the relative position of the adjusting member 33 and the inner rotating member 32 can adjust the state of the lightweight neck brace 1.

[0091] Furthermore, the two limiting grooves 330 can be configured in a figure-eight shape, that is, the distance between the two limiting grooves 330 gradually increases from one end to the other.

[0092] Furthermore, the adjustment part 30 may also include an elastic connector 34, wherein the adjustment part 33 is mounted on the head support part 10 and is elastically supported by the elastic connector 34.

[0093] The elastic connector 34 is located in the movable direction of the adjusting member 33. When the adjusting member 33 moves from the first position to the second position, the elastic connector 34 is further compressed. When the adjusting member 33 moves from the second position to the first position, the compressive force on the elastic connector 34 is reduced compared to before.

[0094] The adjusting member 33 can be elastically supported in the first position by means of the elastic connector 34. When the user applies force to the head support 10 and pulls the head support 10 outward, the adjusting member 33 can be adjusted to the second position. When the user releases the force, the adjusting member 33 can automatically return to the first position under the action of the elastic connector 34.

[0095] More specifically, the adjustment part 30 further includes an adjustment part mounting housing 35, wherein the adjustment part mounting housing 35 forms a mounting space 350, wherein the adjustment member 33 is received in the mounting space 350 of the head support 10 adjustment part mounting housing 35, and the end of the head support 10 is movably inserted into the adjustment part mounting housing 35. The fixing seat 322 of the inner rotating member 32 is fixedly mounted to the adjustment part mounting housing 35, thereby being connected to the head support 10 through the adjustment part mounting housing 35. The adjustment member 33 is located between the inner rotating member 32 and the adjustment part mounting housing 35.

[0096] The adjustment member 33 is mounted on the adjustment part mounting housing 35 and on the head support part 10. The adjustment member 33 can be driven by the head support part 10 to move synchronously.

[0097] The elastic connector 34 has a first connecting end 341 and a second connecting end 342 corresponding to the first connecting end 341. The first connecting end 341 of the elastic connector 34 is abutted against the mounting base 333 of the adjusting member 33, or is connected to the mounting base 333 of the adjusting member 33. The second connecting end 342 of the elastic connector 34 is adapted to abut against the mounting housing 35 of the head support 10 adjusting member. That is, the elastic connector 34 is located between the mounting housing 35 of the head support 10 adjusting member and the adjusting member 33. Since the head support 10 can drive the elastic connector 34 to move together, for example, outward, the distance between the adjusting member 33 and the mounting housing 35 of the head support 10 is shortened during this process, thereby compressing the elastic connector 34. Therefore, when the head support 10 no longer carries the adjusting member 33 outward, the compressed elastic connector 34 can naturally extend to reset the adjusting member 33.

[0098] It is worth noting that the reset adjustment member 33 can then drive the head support portion 10 to reset.

[0099] It is understood that this embodiment is described with the inner rotating member 32 installed on the head support portion 10, and the adjusting member 33 is configured to be linked with the head support portion 10. According to another embodiment of the present invention, the inner rotating member 32 can be installed on the support portion 20, and the adjusting member 33 can also be configured to be linked with the support portion 20, so that switching between the adjusted state and the free state can be realized by pulling the support portion 20.

[0100] For the adjusting member 33, the head support portion 10 forms a guide groove 101, wherein the mounting base 333 of the adjusting member 33 is mounted in the guide groove 101 and can move back and forth along the guide groove 101. The guide groove 101 can guide the movement direction of the adjusting member 33, so that when the adjusting member 33 moves outward to the second position, the inner rotating member 32 can be released, and when the adjusting member 33 moves inward to the first position, the inner rotating member 32 can be pressed back against the outer rotating member 31.

[0101] It is worth noting that, according to one embodiment of the present invention, the adjustment member 33 is configured to be electrically driven so that after user operation, the adjustment member 33 can automatically change between the first position and the second position. For example, the user can press a button to change the lightweight neck brace 1 between the adjusted state and the free state.

[0102] Further, the head support 10 includes a first support arm 11 and a second support arm 12, wherein the first support arm 11 is rotatably connected to the first support arm 21 of the support portion 20 via an adjustment portion 30, and the second support arm 12 is rotatably connected to the second support arm 22 of the support portion 20 via another adjustment portion 30. The first support arm 11 is pivotally connected to the second support arm 12. The first support arm 21 is pivotally connected to the second support arm 22. (See attached...) Figures 1 to 6 The first support arm 11 is not shown to fold toward the second support arm 12 in the diagram; please refer to the appendix for details. Figure 7 As shown.

[0103] When the head support 10 is folded toward the support 20, the first support arm 11 can be folded toward the second support arm 12, and the first support arm 21 can be folded toward the second support arm 22, so that the entire lightweight neck brace 1 can be stored in a smaller size.

[0104] It is worth noting that the first support arm 21 and the second support arm 22 form an angle and the angle can be fixed in the adjusted position, and the first support arm 11 and the second support arm 12 form an angle and the angle can be fixed in the adjusted position, so that the lightweight neck brace 1 can be adapted to users of different sizes, such as users with different head sizes.

[0105] Further, please refer to the appendix. Figures 1 to 6 As shown, the lightweight neck brace 1 includes a fixing part 40, which is disposed on the head support part 10 to assist in fixing the head support part 10. In this embodiment, the head support part 10 is supported on the lower jaw of the head, and the head support part 10 does not completely surround the head, leaving some space for the user to wear. The fixing part 40 is disposed on the head support part 10 and can extend between two ends of the head support part 10 spaced apart, thereby better fixing the head support part 10 to the head. The head support part 10 and the fixing part 40 can together form an adjustable wearing channel 100, so that the lightweight neck brace 1 can adapt to users with different head sizes.

[0106] The fixing part 40 may, but is not limited to, being implemented as a strap, a band with Velcro, or a rope, etc.

[0107] The fixing part 40 can be accommodated in the adjusting part 30, and when the fixing part 40 needs to be used, the fixing part 40 can be pulled out from the adjusting part 30.

[0108] Furthermore, the lightweight neck brace 1 includes a functional part 50, which is disposed within the head support portion 10. When the head support portion 10 is supported on the user's jaw, the functional part 50 conforms to the user's jaw and provides support. The functional part 50 can provide a massage effect on the jaw; it may have protrusions or granules to achieve this massage effect. The functional part 50 may also be vibrating, and related power accessories may be installed within the head support portion 10.

[0109] The functional part 50 can be configured to be flexible to allow for fine-tuning of the user's head position. For example, when the user's head is heavy, the functional part 50 deforms more, and when the user's head is light, the functional part 50 deforms less. The functional part 50 can be implemented in the form of plastic, sponge, a cloth bag filled with granules, etc.

[0110] Reference Appendix Figure 8 The illustration shows another embodiment of the lightweight neck brace 1 according to the present invention. This embodiment and the accompanying drawings... Figures 1 to 6 The main difference in the illustrated embodiment is the adjustment part 30, which in this embodiment is implemented as a torsion spring connected to the head support part 10 and the support part 20 respectively.

[0111] The head support 10 is supported by the support 20 via the adjustment part 30. Because the torsion spring has two extended arms, the angle between the two extended arms cannot be further reduced within a certain range due to its elasticity. When the user wears the lightweight neck brace 1, the head support 10 and the support 20 apply forces to the adjustment 30, such as the weight of the head, causing the angle between the two extended arms of the torsion spring to decrease. Once the two extended arms of the torsion spring decrease to a certain range, the user cannot continue to move their head downwards; that is, the user cannot lower their head.

[0112] When a user wants to adjust the lightweight neck brace 1, the user can only adjust the lightweight neck brace 1 upwards so that the two extension arms of the torsion spring can be extended. That is, the head support portion 10 of the lightweight neck brace 1 can be adjusted unidirectionally relative to the support portion 20, and can be adjusted unidirectionally away from the support portion 20.

[0113] According to another aspect of the present invention, the present invention provides an adjustment method for the lightweight neck brace 1, wherein the adjustment method includes the following steps:

[0114] The head support portion 10 and the support portion 20 of the lightweight neck brace 1 are switched between the adjusted state and the free state by means of the outer rotating member 31 and the inner rotating member 32 of the adjustment portion 30. The head support portion 10 and the support portion 20 of the lightweight neck brace 1 are rotatably connected by the adjustment portion 30. The head support portion 10 is adapted to support the head and is supported by the support portion 20. The support portion 20 is adapted to be supported by the torso. When the inner rotating member 32 is engaged with the outer rotating member 31, the lightweight neck brace 1 is in the adjusted state. The head support portion 20 of the lightweight neck brace 1 can rotate unidirectionally away from the support portion 20, but cannot rotate towards the support portion 20. When the inner rotating member 32 is disengaged from the outer rotating member 31, the lightweight neck brace 1 is in the free state. The head support portion 20 can rotate arbitrarily towards or away from the support portion 20.

[0115] According to an embodiment of the present invention, in the above method, the position of the inner rotating member 32 is controlled by the adjusting member 33, and the lightweight neck brace 1 can be changed from the adjusted state to the free state by pulling the adjusting member 33.

[0116] According to an embodiment of the present invention, in the above method, the position of the inner rotating member 32 is controlled by the adjusting member 33, and when the adjusting member 33 is released, the lightweight neck brace 1 automatically changes from the free state to the adjusted state.

[0117] According to one embodiment of the present invention, in the above method, the head is massaged by the head support portion 10.

[0118] According to one embodiment of the present invention, in the above method, the included angle formed by the first support arm 11 and the second support arm 12 of the head support portion 10 is changed to accommodate heads of different sizes.

[0119] According to another aspect of the present invention, the present invention provides an adjustment method for the lightweight neck brace 1, wherein the adjustment method includes the following steps:

[0120] The head support portion 10 and the support portion 20 of the lightweight neck brace 1 are switched between the adjusted state and the free state by means of the outer rotating member 31 and the inner rotating member 32 of the adjustment portion 30. The head support portion 10 and the support portion 20 of the lightweight neck brace 1 are rotatably connected by the adjustment portion 30. The head support portion 10 is adapted to support the head and is supported by the support portion 20. The support portion 20 is adapted to be supported by the torso. When the inner rotating member 32 is engaged with the outer rotating member 31, the lightweight neck brace 1 is in the adjusted state. The head support portion 20 of the lightweight neck brace 1 can rotate unidirectionally away from the support portion 20, but cannot rotate towards the support portion 20. When the inner rotating member 32 is disengaged from the outer rotating member 31, the lightweight neck brace 1 is in the free state. The head support portion 20 can rotate arbitrarily towards or away from the support portion 20.

[0121] According to one embodiment of the present invention, the connecting arm 321 of the inner rotating member 32 is controlled by the adjusting member 33. In the adjusted state, the connecting arm 321 is controlled to press against the single row of one-way teeth 311 of the outer rotating member 31 so that the outer rotating member 31 and the inner rotating member 32 can rotate relative to each other in one direction. In the free state, the connecting arm 321 is controlled to disengage from the one-way teeth 311 of the outer rotating member 31 so that the outer rotating member 31 and the inner rotating member 32 can rotate freely.

[0122] According to one embodiment of the present invention, the inner rotating member 32 is controlled by changing the position of the adjusting member 33. When the adjusting member 33 is in the first position, it is in the adjusted state. When the adjusting member 33 moves to the second position, the connecting arm 321 of the inner rotating member 32 is driven to disengage from the outer rotating member 31, thereby being in the free state.

[0123] According to one embodiment of the present invention, the adjusting member 33 is controlled by pulling the head support 10, thereby controlling the inner rotating member 32. When the head support 10 is pulled outward, the adjusting member 33 is driven to the first position and is in the adjusted state. When the force exerted by the head support 10 on the adjusting member 33 weakens or disappears, the adjusting member 33 can be reset to the first position.

[0124] According to one embodiment of the present invention, the adjusting member 33 is controlled by pulling the supporting part 20, thereby controlling the inner rotating member 32. When the supporting part 20 is pulled outward, the adjusting member 33 is driven to the first position and is in the adjusted state. When the force applied by the supporting part 20 to the adjusting member 33 weakens or disappears, the adjusting member 33 can be reset to the first position.

[0125] According to one embodiment of the present invention, the adjustment member 33 located in the first position can automatically reset to the second position and can drive the head support portion 10 to reset.

[0126] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved.
